Button-fastener.



ipraeca The sliding link 92, as shown, is turned up at right angles at the end opposite the follower and carries a pivot 98 by which it is connected to a plate 99, forked or slotted at 100 to engage a stationary pivot pin 101 on the frame, the plow 81 being rigidly secured to the plate 99 by any suitable means, as rivets 102. The follower 94 is held in contact with the cam surface by means of a tension spring d connected at one end to the plate 99 andat the other to a pin on the machine frame.

As 1 have pointed out, the link 92 is a rigid member sliding in a fixed rectilinear guide-way 93 so that all parts of the link 92, including the pivot 98, move in a straight line and as the lower end of the plow is immediately adjacent the pivot 98, the plate 99 being rigidl connected to the plow, said end of the p ow likewise has a substantially parallel motion, the slot'100 moving up and down relatively to the pin 101 to compensate for the variation of the path of the pivot 98 and the point of the plow 103 from a true circular arc. Thus we have not only a cl ange of position but a change of direction of the guide sufiicient to provide for the change irection or angle to each other which the two parts of each flap 27 are set.

It will be noticed that the bottom folder rollers, which may be properly termed pressing rollers 85, have their full diameter sections *6 so placed that they contact directly in line with the ends of the plows so that the blank with the flaps turned over and pasted is received immediately into these rollers which engage the edges, particularly the folded flaps, pressing them tightly into place and completing the operation of the pasting.

From the folder rollers, the seal passes downward between the belt 105 and the drying wheel a small pulley 107 on the drive shaft 108 and passing over guide pulleys 109, 110, 111 and 112, spaced about the periphery of the drying wheel which is driven in any suitable manner, as by a belt 113 from a pulley 1141 on the shaft of the lower doubling roller and train of gearing 115.. After passing around the drying wheel between the drying wheel the belt which servesto hold them in pasted position, the seals or envelope partially dry, sufficiently to keep them in a folded or pasted position until completely dry, and they are accordingly delivered from the machine at the point where the belt passes around the pulley 112.

While the operation of the machine has been brought out in connection with the description, it will be reviewed for the purpose of clearness.

The paper web in the roll 3 is drawn over the take-oft rollers 6 by the feed rollers 8 and 9 whence it is fed to the cutting roll- 106, the belt being driven by I ers shown as equal in circumference to the length of the blank provided with a blade or cutter on the upper roller of an outline similar to the blank as shown in Fig. 12, but having a gap or opening 23 in the transverse portion 120 corresponding to the ends 2 1 and% which, it will be understood, are preferably formed by this single cutting edge severing the rear end of each blank from the forward end of the next succeeding blank. The blanks are intended to be led through the machine, each being drawn forward byv the next preceding and therefore kept connected in the form of a single piece of material until severed by the blade 75 on the folding roller 5 which is of a width equal to or slightly greater than the aforesaid gap in the transverse portion of the blade. From the cutting rollers, see Fig. 6, the blanks thus connected are led forward to the scoring rollers, the upper one of which is provided with a blunt edge in the form of the dotted lines on the blank, see Fig. 12. Th blunt edge is pressed against the paper which is supported on the lower roller compressing the fibers along the line thus-engaged, forming a score or line along which the paper is easily folded without cutting or weakening the fiber. From the scoring rollers, see Fig. 7, the blanks still connected as described, are led to the paste rollers, the

upper roller of which is formed with a raised portion 17, see Fig. 8, conforming to the outline of the flaps 27, 28 and 29 between the dotted lines 30 and the outer edges of the blank. These raised portions are coated with paste by means of the roller d4 fed from the paste pot 15. From the paste rollers, the blanks are fed forward to the doubling rollers and 51 which operate as already described, the center of the blank defined by line 26 in F ig. 12 being gripped by the blade 61 and the forward face of the notch in the roller 50 so'that the creased edge at the centeriof the blank is fed forward and downward between the lower doubling roller 60 and the roller 56, the ends 24; and :25, see Fig. 12, being doubled together and the connection between this blank and the next succeeding blank being cut by the blade 7 5 on the top roller 51 acting in conjunction with the cutting block 76 on the lower roller 50. From here the blank goes to the folding rollers and plows 80 and 81 which turn the edge flaps 27, 28 and 29, already paste-coated as described, along the dotted lines 30 and over the adjacent edges of the smaller and flapless portion of the blank. The blank with the flaps thus folded is then fed downward to the drying wheel, whence it is delivered in finished condition.

I have thus described my invention specifically and in detail in order that its nature and operation may be fully understood;

BUTTON-FASTENER.

Specification of Letters Patent.

Patented Feb. 6, IQIK.

Application filed July 1, 1915. Serial No. 37,552.

To all whom it may concern:

Be it known that I, ANDREW G. BRANDT, a citizen of the United States, residing at Scranton, in the county or" Lackawanna and State of Pennsylvania, have invented a new and useful Button-Fastener, of which the following is a specification.

The device forming the subject matter of this application is a button, and the invention aims to provide novel means whereby the eye-forming element may be maintained detachably interlocked with the body.

In the accompanying drawing :-I*igure 1 is a r elevation showing the button hereinafter described; Fig. 2 is a section taken in a plane parallel to the body portion of the button; Fig. 3 is a transverse section; Fig. dis a front elevation.

In carrying out the invention as shown in Figs. 1, 2, 3 and l, the body portion of the button appears at 2% and is provided with a transverse groove 25 in which is mounted a loop-shaped strip 26 comprising spaced walls. In one end of the loop-shaped strip 26 there is fashioned an opening 27, the other end of the strip being formed into a bearing 28. Slidably mounted between the walls of the strip 26 and movable in the opening 27 is a fastening member 31 in the form of a link having converging arms, the fastening member surrounding a securing device 29 which holds the strip '26 to the body 2a of the button, the securing device having a head 30 engaging the outer face of the body it of the button as shown in Fig. I. Mounted to rock in the bearing 28 is the intermediate portion 32 of an eye-forming member or hasp comprising U-shaped, resilient arms 33 disposed parallel to each other, the ends 3 of the arms 33 being pointed, and being provided with shoulders 35. The pointed ends 34: of the arms 33 pass through openings 36 in the outer wall of the loop-shaped strip 26 and through openings 38 in the inner wall of the strip, the ends 3% entering recesses 37 formed in the body portion 24.

In practical operation the hasp is swung over in the bearing 28 until the ends 3e oi the arms 83 pass through the openings 36 and 38 in the loop-shaped strip 26, the shoul der interlocking with the outer wall of the strip Then, it the fastening member 31 be advanced into the position of Fig. 2, its side arms will coast with the ends of the arms 3 of the eye-forming member and maintain the shoulders interlocked beneath the outer wall of the strip 26.

Having thus described the invention, what is claimed is 1. In a button, 'a' body; a keeper assembled with the body; an eye forming member pivotally assembled with the keeper and comprising arched arms adapted to interlock with the keeper; and a wedge slidable on the keeper and coacting with the arms to hold the arms interlocked with the keeper.

2. A button comprising a body; a loopshaped strip 011 the body and comprising spaced walls, one end of the strip being formed into a bearing, and the other end of the strip having an opening; a securing device connecting the strip with the body; a U-shaped eye forming member mounted to rock in the bearing and including arched resilient arms, the strip having openings in wnichthe ends of the arms are received; and a wedge-shaped link surrounding the securing device and mounted to slide between the walls of the strip, the link being accessible through the first specified. opening, and enacting with the inner edges or the arms oil? the eye forming member, adjacent the ends of said arms.

In testimony that I claim the foregoing as my own, I have hereto aiilxed my signature in the presence of two witnesses.

ANDREW G. BRANDT.
